Eutyrannosauria

Eutyrannosauria is a clade of tyrannosauroid theropods whose distribution has been found in what is now Asia and North America.[1] The clade consists of an evolutionary grade of tyrannosaurs such as Appalachiosaurus, Dryptosaurus, and Bistahieversor which led up to the family Tyrannosauridae.[2][3][1] The group was named in 2018 by Delcourt and Grillo in their paper about possible southern hemisphere tyrannosauroids and the phylogeography of tyrannosaurs.[1]
